Abstract (en)
Sealing arrangement for an auger mounted within a container for particulate material, comprising a threaded sealing member (14) adapted to engage the auger flight (21) and to be driven along the auger housing on rotation of the auger. The sealing member is a sliding fit within the auger housing (11, 13) but is restrained against rotation about the auger axis. On first rotating the auger in its working direction the sealing member (14) travels along the auger until it passes beyond the end of the auger flight (21) into a non-functional storage position (23).
